No matter where the destination, chances are you're going to be out of your usual comfort zone when traveling abroad. When I embarked on a two-week trip across parts of Europe last year, I began to feel homesick after a couple days and wasn't enjoying my "trip of a lifetime."

Fortunately, I discovered that my friends had tucked a few pictures of themselves in my bag before I left. This gave me a little piece of home to carry along with me.

Therefore, when leaving home for a period of time, it's a good idea to bring something familiar with you, to quell any sadness. Whether it's a picture, blanket, or favorite snack pack, a comfort item can handily ward off being homesick.
